Bathtub curve – a useful tool to understand failure rates

One particular figure is very commonly used when reliability is discussed: a bathtub curve. The bathtub curve shows the failure rate of a product as a function of time. Thus, it is a description of various failure rates for products over their lifetime. An example of...

Why it is important to consider also absolute humidity when choosing humidity test conditions

Humidity testing is one the most commonly used accelerated reliability test methods. This makes sense since high humidity level is a one of the most common reasons to cause failures. Moreover, humidity testing is relatively easy to conduct and equipment for it is...

How to conduct failure analysis

Failure analysis process is used when something fails, and we need to know how and why it happened. The process itself may be very complex with numerous different analysis methods and tools. However, the overall process itself is typically quite simple and does not...

Unstable resistance – Why flexible electronics should be monitored in real-time during testing

Flexible electronics means applications build with flexible substrates and materials, enabling bending and stretching of the applications. Therefore products which would not be possible with traditional electronics can be accomplished. Application such as wearable and...
Overstress vs wear

Overstress vs wear

Failures are caused by various factors. If we forget early failures, a failure can be caused by a overstress or wear. These two...
